REMOVAL
The water pump on all models can be replaced without discharging the air conditioning system.

WARNING: DO NOT REMOVE PRESSURE CAP WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR.

NOTE: It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of engine coolant is evident on water pump body from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.

Drain cooling system. Refer to Cooling System, Service and Repair, Service Procedures.
Remove accessory drive belts.
The water pump is driven by the timing belt. Refer to Engine for component removal to provide access to water pump.

Remove water pump mounting bolts. Note position of longer bolt for proper re-installation.
Remove water pump body from engine.

INSTALLATION

Clean all O-ring surfaces on pump and cover.

Apply Mopar(R) Dielectric Grease or equivalent to the O-ring to facilitate assembly. Install new O-ring on water pump.
Position water pump to engine.
Install mounting bolts and tighten to 12 Nm (105 inch lbs.).
Install timing belt. Refer to Engine for procedure.
Install accessory drive belts.
Fill cooling system.
